Specification forming part of Letters Patent No.

[77,969, dated May 30, 1876; application filed March 8, 1876.

To all whom it may concern:

Be it known that I, GEORGE A. STANBERY, of Zanesville, Ohio, have invented an Improvement in the Manufacture of Flooring- Tile, of which the following is a specification This machine is designed to manufacture tile or brick out of clay that has been ground up fine or pulverized, andin thatstate pressed dry or semi-dry into the tile. The pulverized clay is placed in the hopper a. The machine is. then ready to start. The side-draft cam 01 moves the die b, which is fastened to the sliding table 0, under the hopper a, so that the die receives a charge of clay. The side-draft cam d then takes the die I) back to its place of rest under the top plunger e. As soon as it reaches this point the top plunger 6, which has the platen f fastened to its lower end, is forced down on topof the die by the revolving cam E, which closesthe top of the die. The platen f is larger than the opening in the die, so that itis perfectly closed. The plunger 0 now remains stationary, whilethe part of the cam E which is a true circle revolves over the roller m, which is fastened in the end of the top plunger 6.

.While the platenf is down and stationary,

.the cam 70 starts to push up the lower plunger n by pushing against the roller 0. The plunger 11. has the punch p" fastened to its top end. 1 This punch fits in the die 12 and forms its bottom. The raising of the punch 10 by the re- "olving cam 70 compresses the clay, so that when the place marked 2 on the cam is has reached the roller 0, the tile is of the right thickness. When the cam It has reached this point the top cam E has revolved so that the point marked 3 on it has reached the roller m, which relieves the plunger 0 and platen f, and allows the weight It to raise them off of the die b. The point marked 4 on the cam k now strikes the plunger n, which raises thetile clear out of the die I). The side-draft cam d now commences to move the sliding table 0 and die I) out from'under the hopper a to receive a fresh charge of clay, and by so doing brings the pressed tile, which is resting on top of the punch 10, in contact with the edge tile off of the punch 19 onto the tables; and as the die b goes under the hopper a to receive a fresh charge of clay, the punch 10 is drawn .down to its place by the pin t, which is fastened into the plunger a, coming, in contact with the inclined plane a. This inclined plane is adjustable, so that the punch can be drawn more or less to suit different charges of clay. The side-draft cam (I again moves the die to its place of rest under the platen f to be pressed, and the tile which has just been pressed lies on the table 8, ready to be removed. As thedie moves out from under the hopper the table 0 closes it, so that no clay can escape.

The canis E, Jr, and d are revolved by the gear-wheels h and I. They both gear into the pinion W, which has the band-wheel Y. and balance-wheel X fastened on the same shaft with it. Dies and punches of different forms can be used to produce difierent-shaped tile.

What I claim as my invention, and desire to secure by Letters Patent, is-

The machine as described, having its platen fiat and larger than the opening in the die, and a movable punch or bottom fitting within the die, to which power is applied for compressing the pulverized clay in a dry or semi dry state, for the substantially as set forth.
